OSCAR plot of Person Without Sleep Apnea

[AquaMan]

Does anyone know where I can find and/or see OSCAR plots / data of persons who don't have clinical sleep apnea?

I'm talking about person who, for whatever reason, is exhibiting on average less than 5 events per hour and none more than 10 seconds.


I realize this is probably a rare thing because people without sleep apnea rarely do sleep studies, and very few people who shouldn't get a machine end up getting one, and people with sleep apnea don't usually get better.

Possibilities are:
1. misdiagnosis of sleep apnea, person gets and uses of machine on regular basis keeps data, rediagnosis confirms no sleep apnea 
2. studies or research
3. person with sleep apnea and machine, sees ENT doctor find out root cause is particular bit of tissue (a unique problem) that can be fixed by surgery.  After surgery sleep study reveals no longer clinical levels of sleep apnea, use machine at home just to see what the numbers are.

There may be more... but does anyone know where I can find this kind of data / OSCAR plot, or does anyone here have some data?

What you are asking is a certain impossibility. OSCAR only reports data from a CPAP. Since a CPAP is only used for sleep apnea to overcome apnea events, how would you determine a person without apnea as opposed to one having it corrected by CPAP? What you need is data from a Polysomnography test, not OSCAR.

    Not directly, but you can see how 'normal' looks by the pattern of the graphs.

Hi Crimson Nape.  Thank you for the reply.

In my humble opinion, claiming that what I am asking for is a "certain impossibility" is an overstatement.


Some examples of possibilities I mentioned are:

1. misdiagnosis of sleep apnea, person gets and uses of machine on regular basis keeps data, rediagnosis confirms no sleep apnea 

Further Explanation: John has problems with sleep but does not have clinical sleep apnea. (Events are below 5... maybe 4?) John had a misdiagnosis during a sleep study (not all doctors are infallible or perfect) and was prescribed a machine, or prescribed to do a trial on a machine.  John uses the machine and keeps the data also creating an OSCAR analysis of the data.  This constitutes the data I'm looking for.  After some time John finds a new doctor and gets a new sleep analysis, and confirms he in fact does not have clinical sleep apnea.


2. studies or research

Further Explanation:  Some institution wishes to study the effects of treatment by the machine, on people who don't have clinical sleep apnea for comparison.  This could highlight consequences of misdiagnosis, and also provide data which could be used as "signatures" indicating that the person using the machine does not have clinical sleep apnea.

People who have sleep trouble agree to participate in the machine study BEFORE any sleep study or diagnosis of sleep apnea.  After the machine study and data is taken,  sleep studies are done for the participants.  Data is gathered about what the machine reports and does for a person who in fact does not have sleep apnea in comparison to those who do have it.

I don't know if anyone (manufacturer, university, government) has done such a study.


3. person with sleep apnea and machine, sees ENT doctor find out root cause is particular bit of tissue (a unique problem) that can be fixed by surgery.  After surgery sleep study reveals no longer clinical levels of sleep apnea, use machine at home just to see what the numbers are.

Further Explanation:  Robert has an odd structural birth defect in the back of his throat.  Robert also has sleep problems.  For whatever reason, his doctor suggests he take a sleep study with a sleep doctor without ever referring him to an ENT doctor to examine any part of him physically.  The sleep doctor suggests a sleep study again with no referral to any ENT doctor.  The sleep study confirms sleep apnea but makes no finding about the specific physical causes being his birth defect.  Robert is prescribed a CPAP machine on a trial basis.  After choosing to go to an ENT doctor to investigate further, the ENT discovers Robert's specific problem and suggests surgery for his birth defect.  Robert undergoes surgery and follows up with another sleep study which confirm he no longer has clinical sleep apnea.  Before returning or donating or selling his machine Robert decides to take some data with his CPAP machine to compare it, and does so creating an OSCAR analysis.

There may be other possibilities....


Kind Regards.

In that case set your machine for a min=max =0 then download the results to OSCAR.

That sets up your machine to not treat any events and just report what occurs naturally.

Obviously that cannot be done. The best any CPAP can do is show that you are well treated at the chosen settings. It cannot prove the absence of apnea. A PSG is needed for that.
